Although the implication of leader-member exchange (LMX) differentiation for work attitudes and behaviours has been documented in the literature, its unique impact on creativity in work teams remains largely unknown. In this study, we develop an integrated model of LMX differentiation and creativity. Specifically, two new concepts - perceived competition and perceived cooperation are proposed as new concepts that will act as mediators to transmit the effect of high/low LMX differentiation on creativity. Procedural justice climate is also theorized as a moderator to influence the relationships between LMX differentiation and perceived competition and perceived cooperation which in turn mediate the effect of LMX differentiation on creativity. We conclude with a discussion of implications of our model for theory and practice
